["In situ dual-modal detection of electrophysiology (EP) and blood oxygen (BO) during muscle-vascular activity is crucial for healthcare and human-machine interaction. It requires an integrated monitoring system: a transparent electrode for EP detection directly adhered to skin and a near-infrared spectroscopy (NIRs) layer for BO detection. In particular, the multi-channel, highly transparent, stretchable electrodes should be well developed. In this study, 16-channel transparent ionotronic electrodes are fabricated based on a stretchable and printable ionogel, demonstrating excellent properties such as high transparency, large stretchability, wet adhesion, biocompatibility, softness, and long-term stability. The electrode exhibits stable contact impedance for 24 h and a 2-week periodic EP monitoring. The 16-channel transparent ionotronic electrode outperforms stretchable gold electrodes by providing stable EP monitoring with minimal interference in NIRs for blood oxygen detection. An in situ negative correlation is found between EP intensity and blood oxygen level over time. This study paves the way for designing transparent ionotronics for synchronous optical-related monitoring and highlights the potential use of an in situ dual-modal monitoring system for the study of muscle-vascular coupling in neurocience and rehabilitation.","Transparent multi-channel ionotronic electrodes are designed to monitor electromyographic signals, and the near-infrared spectroscopy (NIRs) can pass through the ionotronics to detect blood oxygen. In situ dual-modal muscle-vascular monitoring is achieved by combination of the transparent multi-channel ionotronic electrode and NIRs array.image"]
